Scientists from the University of Southampton have discovered an important way that the immune system can learn to recognize and fight cancers. The team, led by Professor Aymen Al-Shamkhani and funded by Cancer Research UK, has shown that a protein called Akt, is vital for the way the body remembers a cancer it has eradicated....

Stem cells beat the clock for brain cancer
New research has shown that human skin cells can be transformed into stem cells, and used to hunt down brain cancer Glioblastoma is an aggressive form of brain cancer that kills most patients within two years of diagnosis. In tests on mice last year, a team at the University of North Carolina at Chapel Hill...

Multiple sclerosis: 'Resetting' immune system may achieve long-term remission
More than two thirds of patients with relapsing-remitting multiple sclerosis, who were treated with a combination of high-dose chemotherapy and stem cell transplantation, have been in remission for 5 years, according to the results of a small clinical trial. Researchers suggest that a combination of high-dose chemotherapy and stem cell transplantation could lead to long-term...

A quarter of adults in the U.S. have hearing loss because of noise
Forty million American adults have lost some hearing because of noise, and half of them suffered the damage outside the workplace, from everyday exposure to leaf blowers, sirens, rock concerts and other loud sounds, the Centers for Disease Control and Prevention reported Tuesday. A quarter of people ages 20 to 69 were suffering some hearing deficits,...

Scientists Have Created Genetically Modified Cows That Are Resistant to Deadly Disease
IN BRIEF Using a new version of CRISPR, researchers were able to genetically engineer cows, making them resistant to bovine tuberculosis. This innovation could dramatically reduce the overuse of antibiotics in livestock, and have a great impact on developing countries. CRISPR COWS Bovine tuberculosis is a disease that affects cows, but can also be transmitted...

How breaks in DNA are repaired
The results are significant for gene therapy procedures and for our understanding of cell transformation. A team of researchers from the biology department at TU Darmstadt has discovered that the processes for repairing DNA damage are far more complex than previously assumed. The ends of breaks in the double helix are not just joined, they...

Roam Robotics' lightweight, inexpensive exoskeleton for the masses
Roam Robotics hopes to use pneumatics and lightweight materials to bring exoskeletons to the masses If the vision of San Francisco startup Roam Robotics and its co-founder Tim Swift are fully realized, we could be buying commercial lightweight exoskeletons to run faster, hike further and lift more with less effort in the coming years. While still in early...
